Winning games question

That's very unlikely to happen but if that does happen, the giveaway maker will just request a re-roll.

It will never happen

Just don't accept the second win, the creator of the giveaway will ask for a reroll. If you want you could tell him directly, without waiting for him to realize. :)

If you think they may send keys, add both on Steam and try to tell them before they email out. If you get hold of both, you can then tell the creator of the first one you won it is OK to give the key now and tell the second to reroll. If you get sent one key, then you have to accept that one and get the other rerolled.

If they are gifts, it doesn't matter, you can send those back.

Think how rare wins are, now think of how unlikely it is for you to win the exact game twice.

It happens and people usually go for a reroll but it doesn't happen often.

you say: hey, thanks for the giveaway, but I already won that. Then he goes to support and asks for a "reroll", this means he asks them to make someone else win the game, and a new winner gets red ties
